I will build secure rest apis with asp net core and c sharp


Level 1
About this gig
Looking for a clean, secure REST API built with ASP.NET Core?
I build professional backend APIs using C# and ASP.NET Core that are secure, well-structured, and ready for production. This gig is for businesses and developers who already have a frontend, mobile app, or system and need the API layer behind it.
What I can build for you:
- Custom REST APIs built from scratch
- JWT authentication and role-based access control
- Database integration with SQL Server or MySQL using Entity Framework Core
- Swagger and OpenAPI documentation
- Third-party API integrations (Stripe, Twilio, Zendesk, Firebase, Google Maps, Damoov)
- Fixing or extending an existing .NET API
Technologies:
- ASP.NET Core
- C#
- Entity Framework Core
- SQL Server
- MySQL
- JWT and OAuth2
- Swagger and OpenAPI
- LINQ
- Postman
- Git
- Twilio SMS
- Stripe and Zendesk
- Firebase
- Google Maps API
- Damoov Telematics
You will receive clean, documented, production-ready source code, not a prototype.
Need a full web application built from scratch instead? Check my other gig.
Message me before ordering so we can confirm scope and the right package.

Yes, Third-party API integrations are included from the Standard package and above. This covers payment gateways, email services, and most external REST APIs.
